The device has addressing support so multiple devices can be driven whilst residing on a serial bus Being a 7 segment display it is not possible to display all alphanumeric characters so this display is primarily for numeric data Overview Requirements The module requires a serial input either RS232 or RS485 which supplies the data to display followed by a carriage return The baudrate is selectable from 9600 to 115200 but is fixed at 8 data bits 1 stop bit and no parity Configuration Configuration is by DIP switches where the baudrate and address can be set Operation The display accepts ASCII data and on receipt of a carriage return character decimal 13 hexadecimal OD the data will be displayed Physical Connections Single PC Connection Connect power to The Power In connector q sui ON IM OFF Connect to the serial bus using either J1 or J4 for RS232 or J2 for RS485 J3 9 Way D Socket RS232 Pinouts CTS Tx Rx GND GND B GND GNDGND RS232 RS485 POWER OUT POWER IN Y v A o o o I o 9 Ji J2 3 RX In View f insid iew from inside case 5 GND J4 has been designed to enable a quick connection to a PC for testing by using a 9 way D cable extension pin to pin and connecting to the PC 9 way D socket Mantracourt Electronics Limited SerialDis User Manual Multidrop RS232 on M orr SW1 set for baudrate of 19200 and an address of 1 lef
